How much S80 T6 cambelt change?

Thinking about buying one, and also wondering when it is due? Thanks

T6 cambelt 

Hello, i looked at a few s80 t6's 4 in total all had done under 90k but 3 of them had knackered gearboxes the geartronic seems to be unreliable so got a 2.9 with regular auto and its great, anyway back to your question i think the cambelt is every 93000mls (150000km) or every 8 years. hope this helps.

I remeber seeing various post on here advertsing cam belt changes for 250 quid. one was from a main dealer as well.
